DSNU3353I csect-name - SORT task-prefix: DB2 SORT SKIPPED percent-skipped PERCENT OF ZIIP OFFLOAD REQUESTS

Explanation

This message reports information about the percentage of sort work requests for each utility sort task to Db2 Sort for z/OS® that are eligible for offload to IBM® z Integrated Information Processor (zIIP) specialty engines but are processed by general CPs:

task-prefix

The prefix of the sort work data set used by the utility sort task.

percent-skipped

The percentage of sort requests that are eligible to be processed on zIIP specialty engines but are processed by general CPs instead. This value is -1 if no zIIP specialty engine is installed.

Db2 Sort for z/OS offloads parts of sort processing to zIIP specialty engines to reduce general CP consumption. However, if scheduling work for zIIP specialty engines would cause increased wait time because too many processes compete for a limited number of zIIP specialty engines, the work might be run on general CPs to avoid excessive elapsed time impact.
